IMPROVEMENT IN SPINNING-MULES.

Specification forming part of Letters Patent No. l 92,064,

August 31, 1876.

To all wlw/n it may concern l Be it known that I, SAMUEL GEORGE, of Lowell, in the county of' Middlesex and Goin monwealth of Massachusetts, have invented ,l certain .new and useful Improvements in Spinning-Mules, which improvements are fully set forth in the following specification, reference being had to the accompanying drawings.

My invention relates to devices for shaping the nose of the cop spun on the mule; and consists in adjusting the nose-peg, as hereinafter described.

Figure l is a side view of the quadrant, radial and slotted arm, windingon chain, chainbarrel, nose-peg, screw, ratchet, pawl, lever, and incline; Fig. 2,` a plan ot' the same parts.

A is a part of the frame of' the head-stock of a mule; B, a part of the carriage slips or rails; O, a part ofthe carriage; D, the quadrant-chain or winding-on chain; E, the chainbarrel,on which said chain winds; F, the quadA rant, and G the radial arm, all constructed and operated inthe usual manner. Secured to the head of the'l radial arm G, in the usual man ner, is the usual slotted arm H. In a bearing, J, on the arm Il, is supported the non-traversing screw I. A sleeve, K, embracing the screw I, has a stud, which projetts into the thread ot' the screw. The nose-peg L is attached to the sleeve K, a slot of the arm H.

It is well known that the positionot the noSepeg;l L determines the shape ofthe nose, or upperend, of the cop being spun, and that said nose peg is now commonly set at dii'erent distances from the arm G by a thumbnut, at the discretion of the mule-spinner, who requires much judgment and experience to move the nose-peg at the proper time and to the proper amount. I move the nose-peg by turning the screwI. Further, I make the 1 screw I with such an increasing pitch, increasing` toward the outer end, that by turning the screw equal amounts "at each return holding the pawl against the ratchet.

nd projects from it through the ofthe radial'arm to an uprightztposition the propershape is given to the cop. I also secure a circular ratchet, N, to said screw and apply a lever, O, turning on said screw, and

carrying apawl, P, and a spring, Q, the spring dated June 19, 1871 appnanon'eled An 'inclined plane, E, is secured to the frame A in such a position that when theradial arm G is thrown back to its upright position the outer end of the lever O slides up the inclined plane and turns th-e ratchet N, and with it the screw I throwing the nose-peg to the right ot the drawing and giving eventually the right shape to the cop.

If the number77 ofthe yarn is to be changed either a ratchet with a greater or less number of teeth or a screw having a different relative pitch mustA be used. The ner the yarn spun the slower the nose-peg should travel (from lett to right) on the arm O, and the greater should be the number ot' teeth inthe ratchet, or the more rapid the increasein the pitch ofthe screw, according' as we resort to one or the other means of variation;

Before beginning a new set ot' cops the nose-` peg is brought back to th ted arm H by lifting the pawl out oi' tne ratchet and reversing the'motion of the screw.

Even with the best mules now in use it is necessary to employ a skilled spinner to every pair ot' mules in order to make cops suitable for weaving, and the principal difficulty in making such cops is in giving' aproper shape to the nose of the cops.

With the invention above described, `boys and girls, whose only dut;7 shall be to mend the broken threads, may be employed at small wages, under the supervision otl a competent spinner.

I claim as my inventionl. The combination ot' the screw I, formed with a varied pitch in different parts of' its thread, the studded sleeve K, and the nosef peg L, substantially as and for the purpose herein speciiied.

2. The combination ot' the screw I, the nose-peg L, the ratchet N,the.pawl P, the lever O, and the incline R, as and for the purpose described.
